Description
Technical field
The present invention relates to the automobile Rear Position Lamp guide structures that a kind of light inlet has coupling device, belong to automobile lamp skill
Art field.
Background technique
Currently, automobile Rear Position Lamp mostly uses guide structure, the advantage of light guide is: can largely reduce LED
Number, to reduce the price of entire car light;The light that LED light source can be issued is guided to the light-emitting surface of light guide,
And then LED point light source is made to become uniform area source.Existing automobile Rear Position Lamp light guide, needs to be hidden LED light source,
And lightguide length will be longer than the light-emitting surface of position lamp, uniformity when realizing that position lamp is lighted.But sometimes due to car light
The no enough spatial arrangement LED light sources of the limitation of shell and moulding and light guide, greatly limit application of the light guide in car light.
In addition also it is unfavorable for repairing and replacing LED light source.
Summary of the invention
The object of the present invention is to provide a kind of simple and reasonable for structure, in the case where LED light source is unobstructed, light can be improved
The light inlet led and light uniformity, and be not limited by a space has the automobile Rear Position Lamp guide structure of coupling device.
The technical solution of the present invention in order to achieve the above objectives is: a kind of light inlet has the automobile Rear Position Lamp of coupling device
Guide structure, interior lampshade and reflecting mirror including light guide, with diffusion, it is characterised in that: including the light guide setting
Between lampshade and reflecting mirror, and interior lampshade is located at the front of light guide, is mounted on the LED light source at interior lampshade both ends against light guide
Entering light region;The light guide is equipped with convex block in the front in entering light region and adds positioned at the part that convex block rear portion is used to increase light diffusion
Thick portion, the convex block has the introducing cambered surface for introducing light in LED light source entering light side, and has in the end face of light guide and introduce light
The introducing inclined-plane of line;The light guide is equipped with the multiple angular teeths being totally reflected to light on interior lampshade in the front of convex block, and more
A angular teeth constitutes end head-on reflection area, and the light guide is equipped in the front of local thickening part for light to be totally reflected to instead
The inclined-plane on mirror is penetrated, and inclined-plane constitutes end back side echo area.
Wherein: center of the tooth top angle β of each angular teeth in the end head-on reflection area between 30-80 °, two teeth
Distance L is in 0.7-1.2mm, and the high h of tooth is in 0.5-1.2mm.
The center of circle of introducing cambered surface on the convex block is not overlapped with the center of LED light source (6).
The angle α introduced between inclined-plane and light guide datum clamp face in the entering light region of the light guide is at 1~15 °.
Angle δ between the inclined-plane and light guide datum clamp face of the end back side echo area is at 65~85 °.
The reflecting mirror, which is located in the ray regions for receiving light guide end back side echo area, is equipped with leaky hole.
Automobile Rear Position Lamp guide structure of the invention is that light guide is arranged in interior lampshade and reflection with diffusion
In mirror, interior lampshade is made to be located at the front of light guide, is mounted on interior lampshade in the LED light source at both ends against the entering light region of light guide.This
The light guide of invention is equipped with convex block in the front in entering light region and is used to increase the local thickening part of light diffusion positioned at convex block rear portion, because
When introducing cambered surface of this LED light source from convex block and the introducing inclined-plane from the end face of light guide introduce, set by light guide in convex block front
The end head-on reflection area that the multiple angular teeths set are constituted by light in light guide in transmission process, makes part light in end front
Echo area is totally reflected on interior lampshade in transmission, so that light guide is at the light direction back side when solving to light when LED light source
The partially dark problem in output optical zone domain.The present invention is equipped in the front of light guide part thickening part for light to be totally reflected to reflecting mirror
On inclined-plane, and the end back side echo area that the inclined-plane is constituted sends out light when transmitting in light guide in the part
Raw total reflection, to solve the problems, such as that light source is partially bright in the positive output optical zone domain of light direction, another aspect light is by adding part to add
In thick portion to reflecting mirror, increase light diffusion, when lighting to alleviate when LED light source, this part of light guide by local thickening part
Partially bright problem.Guide structure of the invention is reasonable, simple, without improving to lamps and lanterns, in the unobstructed situation of LED light source
Under, it can be achieved with light guide and light uniformly, and light guide position is not necessarily to exceed its light-emitting surface, therefore not by the sky of lamp body and moulding
Between limit, improve its versatility.The LED light source of interior lampshade end will be arranged in against the entering light region of light guide in the present invention, because
This is hidden without LED light source, convenient maintenance and replacement.
